Moina is a genus of crustaceans within the family Moinidae. [3] [4] The genus was first described by W. Baird in 1850.They are referred to as water fleas, but are related to the much larger Daphnia magna and the larger Daphnia pulex. [5]
Daphnia pulex is the most common species of water flea. [3] It has a cosmopolitan distribution : the species is found throughout the Americas, Europe, and Australia. [ 4 ] It is a model species , and was the first crustacean to have its genome sequenced.

Daphnia magna. According to the World Registry of Marine Species, Cladocera is a synonym of the superorder Diplostraca, which is included in the class Branchiopoda. Both names are currently in use. The superorder forms a monophyletic group of 7 orders, about 24 families, and more than 11,000 species. Many more species remain undescribed.
Daphnia pulex (Cladocera: Daphniidae) These four orders make up a group of small crustaceans commonly called water fleas. Around 620 species have been recognised so far, with many more undescribed. [22] They are ubiquitous in inland aquatic habitats, but rare in the oceans. [11]
Daphnia have a compound eye, and they are known to have an optomotor response. [12] D. pulicaria generally have a body length less than 3mm. [ 3 ] Because of the clear carapace of Daphnia , it is possible to see the heart and digestive tract, which often appears to be green due to the consumption of algae. [ 11 ]
